nope, havent had any issues with overheating, i was worried that the heat from the floor would cause me heat problems, so i put in a sheet of 5/8" MDF under the amp (which also lifted it up out of the well which im guessing would retain a lot of heat and made running wires to it easier since it sat up a little higher),,ive run it as long as 5 hours at a time with no issues
